The rise of western rationalism: Paul Feyerabend's story

I summarize certain aspects of Paul Feyerabend's account of the development of Western rationalism, show the ways in which that account is supposed to run up against an alternative, that of Karl Popper, and then try to give a preliminary comparison of the two. My interest is primarily in whether what Feyerabend called his ‘story’ constitutes a possible history of our epistemic concepts and their trajectory. I express some grave reservations about that story, and about Feyerabend's framework, finding Popper's views less problematic here. However, I also suggest that one important aspect of Feyerabend's material, his treatment of religious belief, can be given an interpretation which makes it tenable, and perhaps preferable to a Popperian approach.     

Challenging Expertise: Paul Feyerabend vs. Harry Collins & Robert Evans on democracy,public participation and scientific authority: Paul Feyerabend vs. Harry Collins & Robert Evans on scientific authority and public participation

This paper compares Feyerabend's arguments in Science in a Free Society to the controversial theory of expertise proposed by Harry Collins and Robert Evans as a Third Wave of Science Studies. Is the legitimacy of democratic decisions threatened by the unquestioned authority of scientific advice? Or does, on the contrary, science need protection from too much democratic participation in technical decisions? Where Feyerabend's political relativism envisions democratic society as inherently pluralist and demands equal contribution of all traditions and worldviews to public decision-making, Collins and Evans hold a conception of elective modernism, defending the reality and value of technical expertise and arguing that science deserves a privileged status in modern democracies, because scientific values are also democratic values. I will argue that Feyerabend's political relativism provides a valuable framework for the evaluation of Collins' and Evans' theory of expertise. By constructing a dialog between Feyerabend and this more recent approach in Science and Technology Studies, the aim of this article is not only to show where the two positions differ and in what way they might be reconciled, but also how Feyerabend's philosophy provides substantial input to contemporary debate.     

Was Feyerabend a Popperian? Methodological issues in the History of the Philosophy of Science

For more than three decades, there has been significant debate about the relation between Feyerabend and Popper. The discussion has been nurtured and complicated by the rift that opened up between the two and by the later Feyerabend's controversial portrayal of his earlier self. The first part of the paper provides an overview of the accounts of the relation that have been proposed over the years, disentangles the problems they deal with, and analyses the evidence supporting their conclusions as well as the methodological approaches used to process that evidence. Rather than advancing a further speculative account of the relation based on Feyerabend's philosophical work or autobiographical recollections, the second part of the paper strives to clarify the problems at issue by making use of a wider range of evidence. It outlines a historical reconstruction of the social context within which Feyerabend's intellectual trajectory developed, putting a special emphasis on the interplay between the perceived intellectual identity of Feyerabend, Feyerabend's own intellectual self-concept, and the peculiar features of the evolving Popperian research group.     

The concept of intelligibility in modern physics (1948)

This is an English translation of Paul Feyerabend's earliest extant essay “Der Begriff der Verständlichkeit in der modernen Physik” (1948). In it, Feyerabend defends positivism as a progressive framework for scientific research in certain stages of scientific development. He argues that in physics visualizability (Anschaulichkeit) and intelligibility (Verständlichkeit) are time-conditioned concepts: what is deemed visualizable in the development of physical theories is relative to a specific historical context and changes over time. He concludes that from time to time the abandonment of visualizability is crucial for progress in physics, as it is conducive to major theory change, illustrating the point on the basis of advances in atomic theory.     

Introduction: Reappraising Paul Feyerabend

This volume is devoted to a reappraisal of the philosophy of Paul Feyerabend. It has four aims. The first is to reassess his already well-known work from the 1960s and 1970s in light of contemporary developments in the history and philosophy of science. The second is to explore themes in his neglected later work, including recently published and previously unavailable writings. The third is to assess the contributions that Feyerabend can make to contemporary debate, on topics such as perspectivism, realism, and political philosophy of science. The fourth and final aim is to reconsider Feyerabend's place within the history of philosophy of science in the light of new scholarship.     

Between relativism and pluralism: Philosophical and political relativism in Feyerabend's late work

Relativism is one of the most problematic terms associated with philosophical discourse, with Feyerabend considered among the most important twentieth century theorists subscribing to it. This paper provides a detailed overview of relativist positions advanced in Feyerabend's mid-to-late work and investigates the associated epistemic and political applications. Emphasis is placed on how Feyerabend supported certain aspects of relativism, and at what stage he rejected others. It is noted that Feyerabend had already imposed limitations on relativism in Farewell to Reason, in which he entertained the possibility of epistemic definition within stable contexts, and advanced the notion that opportunities and equality associated with political and cultural units could only be valid within a democratic system. In Conquest of Abundance, political relativism is largely discarded, while epistemological relativism is increasingly treated as an appeal for diversity in all areas.In this re-reading of his work, it becomes clear that Feyerabend was already advocating a moderate form of epistemic and political relativism in the middle of his career, which he subsequently developed in the direction of “ontological pluralism” in his later work. This paper thus shows that Feyerabend's relativism should not be completely rejected, but rather that it continues to offer interesting food for thought.     

Rediscovering Einstein's legacy: How Einstein anticipates Kuhn and Feyerabend on the nature of science

Thomas Kuhn and Paul Feyerabend promote incommensurability as a central component of their conflicting accounts of the nature of science. This paper argues that in so doing, they both develop Albert Einstein's views, albeit in different directions. Einstein describes scientific revolutions as conceptual replacements, not mere revisions, endorsing ‘Kant-on-wheels’ metaphysics in light of ‘world change’. Einstein emphasizes underdetermination of theory by evidence, rational disagreement in theory choice, and the non-neutrality of empirical evidence. Einstein even uses the term ‘incommensurable’ specifically to apply to challenges posed to comparatively evaluating scientific theories in 1949, more than a decade before Kuhn and Feyerabend. This analysis shows how Einstein anticipates substantial components of Kuhn and Feyerabend's views, and suggests that there are strong reasons to suspect that Kuhn and Feyerabend were directly inspired by Einstein's use of the term ‘incommensurable’, as well as his more general methodological and philosophical reflections.     

Feyerabend's perspectivism

Although, Feyerabend himself seems never to have used the term ‘perspectivism’ to designate a philosophical position, I think his views about science are very well characterized as perspectival. In fact, his later writings contain much that contributes to current thinking about perspectivism. I would like, therefore, to distinguish my own perspectivism from Feyerabend's. In the end, I will argue, his perspectivism is lacking enough of the critical bite that the younger Feyerabend found so attractive in Popper's philosophy.     

Pluralism and anarchism in quantum physics: Paul Feyerabend's writings on quantum physics in relation to his general philosophy of science

This paper aims to show that the development of Feyerabend's philosophical ideas in the 1950s and 1960s largely took place in the context of debates on quantum mechanics.In particular, he developed his influential arguments for pluralism in science in discussions with the quantum physicist David Bohm, who had developed an alternative approach to quantum physics which (in Feyerabend's perception) was met with a dogmatic dismissal by some of the leading quantum physicists. I argue that Feyerabend's arguments for theoretical pluralism and for challenging established theories were connected to his objections to the dogmatism and conservatism he observed in quantum physics.However, as Feyerabend gained insight into the physical details and historical complexities which led to the development of quantum mechanics, he gradually became more modest in his criticisms. His writings on quantum mechanics especially engaged with Niels Bohr; initially, he was critical of Bohr's work in quantum mechanics, but in the late 1960s, he completely withdrew his criticism and even praised Bohr as a model scientist. He became convinced that however puzzling quantum mechanics seemed, it was methodologically unobjectionable – and this was crucial for his move towards ‘anarchism’ in philosophy of science.     

The abundant world: Paul Feyerabend's metaphysics of science

The goal of this paper is to provide an interpretation of Feyerabend's metaphysics of science as found in late works like Conquest of Abundance and Tyranny of Science. Feyerabend's late metaphysics consists of an attempt to criticize and provide a systematic alternative to traditional scientific realism, a package of views he sometimes referred to as “scientific materialism.” Scientific materialism is objectionable not only on metaphysical grounds, nor because it provides a poor ground for understanding science, but because it implies problematic claims about the epistemic and cultural authority of science, claims incompatible with situating science properly in democratic societies. I show how Feyerabend's metaphysical view, which I call “the abundant world” or “abundant realism,” constitute a sophisticated and challenging form of ontological pluralism that makes interesting connections with contemporary philosophy of science and issues of the political and policy role of science in a democratic society.     

Relativism in Feyerabend's later writings

This paper reconstructs, and distinguishes between, Feyerabend's different forms of relativism in his later writings. Science in a Free Society remains close to familiar forms of relativism, while, at the same time, developing an original but under-argued form of political relativism, and rejecting “conversion” models of cultural exchange. Farewell to Reason moves away from common renderings of relativism, and develops a range of different new forms. Central here are links between relativism, skepticism and infallibilism. In the last six years of his life, Feyerabend often criticizes a peculiar radical form of relativism that arguably no-one has ever proposed or defended. In the same context, Feyerabend sketches an “ontological” form of relativism. It combines “Kantian humility”, metaphysical pluralism and constructivism.     

Feyerabend on politics,education, and scientific culture

The purpose of this paper is to offer a sympathetic reconstruction of the political thought of Paul Feyerabend. Using a critical discussion of the idea of the ‘free society’ it is suggested that his political thought is best understood in terms of three thematic concerns—liberation, hegemony, and the authority of science—and that the political significance of those claims become clear when they are considered in the context of his educational views. It emerges that Feyerabend is best understood as calling for the grounding of cognitive and cultural authorities—like the sciences—in informed deliberation, rather than the uncritical embrace of prevailing convictions. It therefore emerges that a free society is best understood as one of epistemically responsible citizenship rather than epistemically anarchistic relativism of the ‘anything goes’ sort—a striking anticipation of current debates about philosophy of science in society.     

Scrutinizing thing knowledge

In his book Thing Knowledge Davis Baird argues that our accustomed understanding of knowledge as justified true beliefs is not enough to understand progress in science and technology. To be more accurate he argues that scientific instruments are to be seen as a form of “objective knowledge” in the sense of Karl Popper.I want to examine if this idea is plausible. In a first step I want to show that this proposal implies that nearly all man-made artifacts are materialized objective knowledge. I argue that this radical change in our concept of knowledge demands strong reasons and that Baird does not give them. I take a look at the strongest strand of arguments of Baird's book—the arguments from cognitive autonomy—and conclude that they do not suffice to make Baird's view of scientific instruments tenable.     

Models and perspectives on stage: remarks on Giere’s Scientific perspectivism

Ron Giere’s recent book Scientific perspectivism sets out an account of science that attempts to forge a via media between two popular extremes: absolutist, objectivist realism on the one hand, and social constructivism or skeptical anti-realism on the other. The key for Giere is to treat both scientific observation and scientific theories as perspectives, which are limited, partial, contingent, context-, agent- and purpose-dependent, and pluralism-friendly, while nonetheless world-oriented and modestly realist. Giere’s perspectivism bears significant similarity to earlier ideas of Paul Feyerabend and John Dewey. Comparing these to Giere’s work not only uncovers a consilience of ideas, but also can help to fill out Giere’s account in places where it is not fully developed, as well as helping us understand the work of these earlier authors and their continuing relevance to contemporary concerns in philosophy of science.     

Was Feyerabend an anarchist? The structure(s) of ‘anything goes’

The near consensus in the secondary literature on Feyerabend is that his epistemological anarchism, characterized by the slogan ‘anything goes’, was not a positive proposal but the conclusion of a reductio argument against his opponents (Lloyd 1997; Staley 1999; Munévar 2000; Farrell 2003; Tsou 2003; Oberheim 2006; Roe 2009). This makes anarchism a mere criticism rather than a substantive position in its own right. In this paper, I argue that Feyerabend held anarchism as a positive thesis. Specifically, I present two possible interpretations of anarchism: one where anarchism is entailed by Feyerabend's radical view of pluralism and another where scientists must be ‘methodological opportunists’, which Feyerabend held simultaneously from at least 1970. I then consider how these positions fare against the more influential criticisms of anarchism (Nagel 1977; Worrall 1978; Godfrey-Smith 2003). I conclude by suggesting two avenues to constraining a literal interpretation of ‘anything goes’ on Feyerabendian grounds.     

Feyerabend,truth, and relativisms: Footnotes to the Italian debate

There is a substantial literature on Feyerabend's relativism—including a few papers in this collection—but fewer specific studies of the ways that his writings and ideas have been taken up among the non-academic public. This is odd, given his obvious interest in the lives and concerns of persons who were not ‘intellectuals’—a term that, for him, had a pejorative ring to it. It is also odd, given the abundance of evidence of how Feyerabend's relativism played a role in a specific national and cultural context—namely, contemporary Italian debates about relativism. This paper offers a study of how Feyerabend's ideas have been deployed by Italian intellectuals and cultural commentators—including the current Pope—and critically assesses them.     

Hilbert's axiomatic method and Carnap's general axiomatics

This paper compares the axiomatic method of David Hilbert and his school with Rudolf Carnap's general axiomatics that was developed in the late 1920s, and that influenced his understanding of logic of science throughout the 1930s, when his logical pluralism developed. The distinct perspectives become visible most clearly in how Richard Baldus, along the lines of Hilbert, and Carnap and Friedrich Bachmann analyzed the axiom system of Hilbert's Foundations of Geometry—the paradigmatic example for the axiomatization of science. Whereas Hilbert's axiomatic method started from a local analysis of individual axiom systems in which the foundations of mathematics as a whole entered only when establishing the system's consistency, Carnap and his Vienna Circle colleague Hans Hahn instead advocated a global analysis of axiom systems in general. A primary goal was to evade, or formalize ex post, mathematicians' ‘material’ talk about axiom systems for such talk was held to be error-prone and susceptible to metaphysics.     

Genetic epistemology,equilibration and the rationality of scientific change

Genetic epistemology is concerned not only with the development of knowledge in the individual person, but also with the epistemological development of scientific thought. If so, problems and solutions in the one area should be roughly isomorphic to problems and solutions in the other area. To illustrate this, I consider Piaget's theory of equilibration and show how this theory has implications for issues concerning scientific progress, change and rationality. Piaget's views about these issues have much in common with claims of contemporary philosophers of science (such as Popper and Lakatos) concerning the rational growth of science, but in addition purport to be grounded in empirical psychology. This suggests thatt it may be fruitful to investigate the possibility of integrating cognitive psychology and philosophy of science in a new way.
